Authentication:Spring Security provides a robust authentication framework, supporting various authentication mechanisms such as username/password, LDAP, OAuth, and more. You can also implement custom authentication providers.
Authorization:It offers fine-grained authorization control, allowing you to define access control rules based on user roles, permissions, and expressions. Role-based and attribute-based access control (RBAC and ABAC) are supported.
User Management:Spring Security simplifies user management tasks, including user registration, password management, and account locking. It integrates with various user stores, including databases and LDAP directories.
Session Management: You can manage user sessions and control session-related settings like session fixation protection, concurrent session control, and timeout handling.Cross-Site Request Forgery (CSRF) Protection: Spring Security provides built-in protection against CSRF attacks by generating and validating CSRF tokens.
Cross-Origin Resource Sharing (CORS): It supports configuring CORS policies to control which domains are allowed to access your application’s resources via AJAX requests.
Security Filters: Spring Security uses a series of filters to process and secure HTTP requests. These filters can be customized and extended to implement various security features.
Form Login and Basic Authentication: Spring Security simplifies the implementation of form-based login and HTTP basic authentication.
Token-Based Authentication: It supports token-based authentication, including JSON Web Tokens (JWT), OAuth2, and OpenID Connect (OIDC).
Method-Level Security: You can secure individual methods or services using annotations like @Secured and @PreAuthorize.
Custom Authentication Providers: Spring Security allows you to implement custom authentication providers, such as integrating with external identity providers or custom authentication mechanisms.
Integration with Spring Framework: Spring Security seamlessly integrates with the broader Spring ecosystem, making it easy to secure Spring-based applications.
Security Events and Auditing: It provides support for auditing security events and monitoring security-related activities in your application.
Extensibility: Spring Security is highly extensible, allowing you to implement custom security features or integrate third-party security libraries.
OAuth 2.0: Spring Security includes features for implementing OAuth 2.0 authorization servers and clients, making it suitable for building secure APIs and enabling single sign-on (SSO) scenarios.
